Abstract
The main directions of improvement of complex processing of nepheline for alumina and passive products are considered. The estimation of promising "dry" method of alumina and portland cement production, problems of aluminum and silicon separation and obtaining coarse-grained alumina of higher qualities, the prospect of expanding the range of products is shown, the comparative analysis of cost characteristics of apatite and nepheline concentrates is given, indicating a higher potential of nepheline raw materials.
